IFIEHQD,`OF OVOSSO, MICHIGAN MIXING Mach-Ime Application filed November Thisinvention is an improvement'in mixing machines, andthe principal objectthereof is to provide a simple, novel, and efficient machine for mixingtogether various ingredients, whereby the ingredients will be thoroughlydiffused, said machine being particularly adapted for mixing balancedrations for stock feed; also for mixing cement, fertilizers, and in factany other materials which must be aerated, dried, mixed in batches, orin proportions by a formula, said machines embodying certain novelfeatures of arrange ment and construction as hereinafter set forth.

I will explain the invention with reference to the accompanying drawing`which illustrates one practical embodiment thereof to enable othersitoadopt and use the same, and will summarize in the claims the novelfeatures of construction, and novel combinations of parts, forwhichprotection is desired.

In said drawing :h

Fig. 1 is a top plan view of the mill, partly broken away.

Fig. 2 is a side elevation thereof, partly broken away.

Fig. 3 is an end elevation thereof, from the hopper end.

Fig. Ll; is an end elevation thereof, from 'the opposite end.

Fig. 5 is an enlarged detail section through the driving mechanism, andthe adjacent end of the drum.

Fig. 6 is a. detail. My novel mill preferably comprises a revoluble druml, having its ends closed by means of castings 5 and 50 bolted theretoas shown in Figs. 5 and 6, said castings being provided with axially'4disposed hub portions 5, 50a respectively journaled in bearings 3,secured to supporting frames 4 at each end` of the drum. The peripheryof casting 5 is provided with gear teeth 5b coaxial with drum 1, saidgear teeth meshing with a p-inion 6, provided on one side with a hubextension 6a, the hub extensions being journaled in a bearing 8,attached to the adjacent frame 4. A sprocket 7 is keyed to the outer endof extension 6a.

Shaft 2 extends axially through drum 1 and castings 5 and 50 said shaftbeing journaled 1, 192s. serial No. 316,386.

in thelhubi of casting 5 as shown. On the end of shaft 2 extension todrum 1 and adjacent casting 5 are located the driving pul leys 9 and 10to be rotated by belts not shown in opposite directions, both of saidpulleys 55 being loosely mounted on a sleeve 11, (Fig. 5) which is keyedor otherwise secured to shaft`2 and revolves therewith. ,On the innerends of the hubs of pulleys 9 and 10 are formed clutch jaws 9, 10, andbetween the pulleys is a sliding clutch 12 which is feath-V ered tothesleeve 11 and movable longitudinally ,thereof by means of a hand lever13 pivoted to a `member il@L of frame 1l. On the outer end of the sleeve11 is placed a set collar Any other means, however, for versmg therotation of the shaft 2 may be used. Between pulley 9 and bearing` 3 onshaft 2 is keyed a sprocket 15 which drives i the sprocket 7 by means ofa chain 16 to ro- 7U tate the drum 1.

Extending into the drum 1, from the opposite end thereof is a fixed opentrough 22 coaxial with shaft 2 in which trough a conveyor screw 18,mounted on shaft 2, rotates while drum l revolves. As shown in Fig. 6,trough 22 extends through the hub of casting` 50, and through theadjacent bearing 3, whereby a continuous,unbroken, passageway isprovided into and out permitting the drum 1 to rotate around the fixedtrougl1122 while shaft 2 is likewise rotating. Within the drum 1, arefour longitudinally and radially disposed plates 23 ati `i tached to thedrum at the ends and inner side C.; of the drum, and to each side ofwhich plates j are secured a plurality of parallel vanes 24 disposed atan angle to the` transverse axis of drum 1, as shown in the drawing, andj slanting preferably towards the `end cast tu ing of'thedrum. .j `Attheendfof drum 1 adjacent casting 50 is located a hopper 17 into whichthe trough 22 and the shaft 2, carrying the conveyor' screw 18,extendswhereby the material may ibe moved in trough 22 by conveyor screw181 into or out of thedrum `Preferably the hopperlfis an integralpart oftrough 22', but may `be made separately, desired,` and j arrangedtowforni a continuation of said of the drum 1, while i? i ofi trough. Inthe outer end of hopper 17 is a bearing forthe shaft 2. The'hopper isprovided with an outlet spout 19 in its bottom,

' .which spout may be opened and closed by operating the slidable plate20. The lower end of spout 19 is provided with a flange to Vwhich a bagB may be secured to receive the n'iateral discharged from spout 19.V Awire screen, 21 is placed in the hopper 17 over Y vthe conveyor screw 18to prevent refuse from entering the container when material is being fedinto same.

The operation of the mixer is as follows The pulleys 9 and 10 areconnected to a suitable source of power by meansfof belts, one being across beltto rotate shaft 2 in opposite directions. IVhen the operatorthrows the clutch 12-into contact with the hub of one pulley,; the shaft2 and screw 18 revolve in the same direct-ionl as that pulley, and thematerial to be mixed is fed into the d rum 1, through the hopper 17, thedrum 1 being revolved in the opposite direction by means of sprocket 15,chain 16, sprocket 7, spur pinion 6,7andgear 5. As the screw 18 feedsthe material into the drum 1, the same overows trough 22 and falls intothe interior of the drum and is picked up and mixed by the plates 23,the vanes 24'feeding the material toward the hopper end of thecontainer. Whenthe mixing is completed, the clutch 12 is thrown to lockagainst the hub of the other pulleyand the rotation of shaft 2 and drum1 is reversed, and the mixed material in trough 22 is then fed towar-dthe hopper end,

p and out through .the hopper -discharge spout scopeof the claims.
